# Question: What is the problem statement of Tower of Hanoi algorithm?

Contents

First, only one disk may be moved at a time. Second, a larger diameter disk may never be placed on a smaller disk. Any number of disks can be used. We first solved it with one disk, then two, and then three.

## What is statement of Tower of Hanoi problem?

Initially, all the disks are placed on one rod, one over the other in ascending order of size similar to a cone-shaped tower. The objective of this problem is to move the stack of disks from the initial rod to another rod, following these rules: A disk cannot be placed on top of a smaller disk.

## Which statement is correct in case of Tower of Hanoi?

Explanation: Objective of tower of hanoi problem is to move all disks to some other rod by following the following rules-1) Only one disk can be moved at a time. 2) Disk can only be moved if it is the uppermost disk of the stack. 3) No disk should be placed over a smaller disk. 2.
